Fans flocked to Twitter to make their disappointment known in regard to The Voice star not being mentioned among the legendary stars who passed away this year, including Gene Wilder, Garry Marshall, Muhammad Ali, Garry Shandling, Doris Roberts, and more.

Because The Voice earned a trophy for Best Reality Competition Show, fans were especially upset over Grimmie's absence — but this isn't the first time the 22-year-old has been left out of an award show since her tragic slaying this June.

On Monday, the brunette beauty took to IG to share a Snapchat filtered pic and to discuss the Teen Choice Awards' touching tribute to the victims of several tragic shootings. It's said, for the now deleted post, Miz Ridley wrote:

While the late celeb won a posthumous award for Choice Web Star: Music, the event opted to leave her out of the powerful tribute to victims of gun violence. It was a very confusing choice given Grimmie's VERY recent death and her huge fan base.

A source close to C.G.'s family complained:

"While we are glad that Christina finally won her much deserved Teen Choice Award, we are also definitely disappointed that her name was not mentioned at any point during the two-hour broadcas. It seems they could have paid honor or tribute to her in some way and that opportunity was missed. The fans have a right to be upset."

All fair points. It's especially frustrating considering they used Christina's name to PROMOTE the broadcast — the least they could have done was mention her name!

Following the snub, fans started a petition against Fox titled, "Request Teen Choice Awards & Fox formally apologize for disrespecting Christina Grimmie". As of now, the petition has about 1,000 signatures.

While the network has yet to respond to the backlash, we wouldn't be surprised if they issued a statement soon.

When it comes to the Teen Choice Awards, stars from the film, music, and TV industries all hit the blue carpet to dish A LOT about what's going in their lives. Luckily, we were able to EXCLUSIVELY chat with some of our favorite celebs and rising up-and-comers while at the exciting event!

But now, the younger sister of Louis, Félicité Deakin (pictured above, left, with Louis), has figured out her own way to pay tribute to her mother in a very special manner, and we are SO touched by it.

On Friday, the 16-year-old Deakin shared the following image (below), a gorgeous portrait of the family with her late mother, Johannah Deakin, surrounded by all of her children:
